. To 'dll whom it may concern:

Be it known that T,-'WILLIAM JMoFAR- LAND, a citizen of the United States, residing at Hebronycounty. of Porter; and State of In diana; have invented certain new and useful Improvementsin Snow-Flows, of which the followingis a specification.

. My invention relates tosnow plows and articularly to horse propelled snow plows or openingroadways in towns and rural districtsv i The'object of my invention is to provide a snow plow which maybe operated as readily inheavy snows as ililighter ones, and one:

whichwill clear away the snow in front of the horses thereby giving 1 them a better and more firm-"footing than is obtained other wise:

A further object of my invention isto pros vide a-snowlow asmentioned, which shall* be readilysa justable.

Other objects will appear hereinafterg front of said frameand-runners and suitable draft gear 1 arranged at the rear end of the frame for hitching horses theretogso that the horses will at all timesbe behind the plowhead; "j

My invention further =consistsin a snow low' as mentioned in which the plow head 7 1s adjustably connected'to the frame; and in I meansfor regulatingthe same. i

My invention further consists in a snow plowas-mentioned, equipped with a suitable steering gear andinvarious' details of construction; andarrangements of. parts all as will be described hereinafter and pa-rticu: I

larly pointed out in the claims.

Fig. 12 is a detail-view illustrating the connection. between the main frame and the the frame which is rigidly connected to and 1 supported by a front sled consisting of a pair. of runners 2 and the transverse member 3, the front end of "the member or beam 1 being connected to the latter. 4-4 are apair of braces eXten ding diagonally from the runners 2 to the beam 1 rigidly bracing the same. The rear end of the beam 1 is supported upon y connected thereto and by means of which, the low is guided. 6 indicates the plow head w ich is orizontal frame or strengthening member 7. The plow head 6 is arranged in front of the front sled and is supported upon a pair of bars or beams 8"8,Which are rigidly connected to the frame members 7 "at substantially their center and extend diagonally rearwardly to meet the beam 1 to which they are pivotally connected. To this end the beam preferably of metal and provided with the With these obj ectsflin view my inventionconsistsgenerally in a suitable frame mount- .ed upon runners; a plow head arranged in 1 is rovided with a pair of castings 9 which A are olted'to the sides t'hereof'tothe rear of the sled and braces 4, and having the sockets 10 to receive the ends of the beams 8. 11

1 indicates a boltpassing through the socket members 9 and the ends of the beams8 frame.

The head of the plow being pivotally connected to-the frame as-above described, is

pivotally connecting the; plow head to the vertically adjustable to raise orlower it with 2" relationto theground, and to this endsui-table mechanism is provided for raising and lowering the head; This "comprises a rack and pinion arranged in suitable; standards. ex-tending upwardly from the transverse member 3 of the front sled.

1 2 .12 indicate the standards which co m prise the parallel side walls 13 and the top 14 connectingsaid walls at. the upper ends. The

lower ends of the walls 13 are flanged as at 15, affordingmeans by whichxthe standards are secured to the member. 8.

w 16 indicates a rack barf. bifurcated. at its lower end and pivotally connected to its re- The bar 16 ex tends through an aperture 17 in the top '14 of the standard which constitutes a guide for the same. Arranged between the walls 13 and meshing with the rack 16 is a pinion 18, the shaft 19 of which extends through the inner wall 13 of the standard and is provided with a hand-wheel 20. turning the hand-wheel, the head 6 will be raised or lowered as desired, also that the standards 12 form guides for the beams 8, reventing lateral displacement of the plow ead.

.21 indicates a platform upon which the operator stands. To hold the head in adj usted for sac of the hand-wheels operated by a foot lever 23.

The rear runner 5 is pivotally connected to the beam 1 at or near its rear end as before mentioned, and suitable means are rovided for turning the runner toguide t e plow. To this end, the runner is provided with a vertical post 24 which is sleeved through the beam 1. The upper end of the post 24,

above the beam isprovided with a segmental gear 25 whichmeshes with a pinion 26 secured to a vertical shaft 27 of a horizontal hand-Wheel 28. I v

29 indicates a seat supported upon the rear end of the beam 1.

30 indicates the casting bolted to the beam 1 and extending above the gear and pinion 25 and 26, and affording bearings for the shaft 27 and the upper end of the post 24. The gear 25 is provided with a plurality of holes 31 which are engaged by a pin 32 to hold the runner 5 at the proper angle. The pin 32 is raised out of engagement with the gear by a foot lever 33 mounted in a bracket 34. When the lever 33 is released, a spring 35 interposed between an arm 36 on the bracket and a collar 37 on the pin, turns it to normal position to enter one of the holes 31.

38 indicates the draft gear to which the horses are attached. This is arranged at or near the rear end of the beam 1 and is arranged for two horses, one upon each side of the beam. It is obvious that the horses bein behind the plow head andthe front sled, will be in the ath cleared by the plow and will therefore ave a better and firmer footing than in those plows in which the horse is arranged in front of the plow head.

Sometimes, when the snow is heavy it is desirable to hitch additional horses to the plow. These cannot be arranged beside the others as such arrangement would bring the additional horses at the point where the snow has been piled up or banked by the plow. Hence they must be arranged behind the others, and to this end, I provide an extension member which is secured to the rear end of the beam 1. This comprises a beam 39 which is secured in alinement with the beam 1 and having its rear end supported It is obvious that by position, I provide a band break 22 by a sled 40. The beams 1 and 39 are connected end to end by a casting 41 secured to the end of the beam 1 by a bolt 42. The

casting com rises the side Walls 43 which fit the'si'deso the beam snugly and the top wall 44, and extends beyond the end of the beam 1. The walls 43 are provided with a pair of vertically disposed slots 45 having the forwardly and horizontally disposed extensions 46, and the beam 3 9,is provided wit1i-. a,

corresponding pair of pins .or lugs47 to engage the slots. After the pins are inserted in the slots, a latch 48 pivotally connected to V the casting is drop ed to engage the pins 47 and hold them in t e slot extensions 46. It

is evident that in this manner, the extension 7 is firmly and rigidly secured to the main beam 1.

As before stated the rear end of the member 39 is supported by the sled 40, however,

a rigid connection cannot be had between the member and the sled as owing to the length of the device, considerable strain would beplaced thereon in passing over uneven ground. I therefore rovide the sled 40 with avertical guide 50 etween the vertical side walls 51 of which the rear end of i the beam 39 is held. The walls51 are slotted as at 52 and a pin 53 extends through the beam 39 andinto the slots 52. The springs 54 arranged above and below the ends of the beam maintain it in normalor central posif tion and permit the beamto rise or fall as it passes over uneven ground. Near the rear end of the beam 39 is arranged the draft gear 55 to: which the additional horses are H in order to cut a path of greater or ess width,

and in Fig. 8 I have illustrated the front end of such a plow, it being understood that the rear end is similar to the form shown in Fi s. 1 and 2. Referring now to Fig. 8 it will be seen that solidfront casting 57 andthe side Wings 58 hingedlyconnected thereto. fication the beams 8 do not extend directly to the plow head but only a short distance in front of the standards 12. The beams then turn inwardly asat 59 to the center of. the device and are provided with an extension 60 to the end of which the casting 57 is secured. It is obvious that the plow head may be adjusted vertically in the same manner as described hereinbefore. 6l61 indicate a pair of rack bars connected at one end to the respective wings 58 and slidably mounted in a boxing 62 arranged at the center of the device.- A pinion 63 on a vertically disposed shaft 64 meshes with the racks 61 and the V Y '7 upper end ofv the shaft 64 is provided with a hand-Wheel 65. It is obvious that by turn ing the hand-wheel the wings 58 Will be the plow head comprises a In this modithe wings in adjusted position.

swung inwardly or outwardly as desired. A ratchet 66 on the shaft and a pawl 67 holds The bearings for the bars 61 in the casing 62 are sufficient to prevent lateral movement or swinging of the bars, hence a sliding connection 68 is rovided between the bars and the wings.

n Figs; 9, 10 and 11 I have illustrated a modification wherein the device is arranged as a one horse plow. In this form a pair of parallel beams 70 extend from the front sled to the rear of the device where they are supported upon a rear sled, the latter comprising a pair of runners 71 connected by a transverse member 72. The sled is ivotally connected to a bolster 73 Which is ingedly connected as at 74 to one of the longitudinal members 70 and detachably connected by a in or bolt 75 to the rear end of the other ongitudinal member. By unfastening the connection 75 the rear sled may be swung out of the way to permit a horse to enter between the longitudinal members after which, it is turned back into position and fastened. 76 indicates the draft gear to which the horse is hitched. The rear sled is provided with a steering gear in all respects similar to that with which the runner 5 is equipped as shown clearly in Figs. 9 and 10. The low head 6 is supported upon a pair of ongitudinal beams 77 arranged directly above the beams 70 and ivotally connected thereto at their rear en s, the beams 70 being provided with castings 78 having sockets 79 to receive the end 80 of the beams 77.. The front sled is provided with mechanism for raising and lowering the plow head which is identical with that illustrated in Figs. 1 and 2 of the drawings and described hereinbefore.
